This doesn't seem warranted given current usage, unless we change our
model here to not care (as much) about usage.

CC-BY 1.0                 2
CC-BY 2.0                 3
CC-BY 2.5                11
CC-BY 3.0               165
CC-BY 4.0                28
CC-BY-SA 1.0              3
CC-BY-SA 2.0             44
CC-BY-SA 2.5             14
CC-BY-SA 3.0            285
CC-BY-SA 4.0             61

4.0 is a pretty niche license right now.  Maybe that's expected to grow at
the cost of 3.0, though....
